CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. $71,501, dated January30, 18853.

4 Application filed November 24, 1882. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN FRANKLIN llIETZ, of Med way, in the countyof Clarke and State of Ohio, have invented a new and 1mproved Car-Coupling, of which the following is a full, clear, and exactdescription.

The invention has for its object to improve the usual means foruncoupling the pivoted wings of a draw-head from an arrow-head link andfor holding the link up in front, so as to he conveniently guided intoan opposite drawhead, as hereinafter described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in

1 which similar letters of reference indicate corresponding parts in allthe figures.

Figure l is an end elevation of my improved car-coupler, partsbeingshown in section. Fig. 2 is a plan view of the same, showing onekind 2-1) of draw bar orlink. Fig. 3 is a sectional plan view of thesame, showing another draw bar or link.

The draw-head A is provided with an inwardly-tapering end opening in theusual man- 2 her, and behind the same the opening in the draw-head isstraight, and provided in each side with a recess or groove, A, adaptedto receive wings B B, placed edgewise and adapted to swing laterally,and rigidly mounted on 0 vertical shafts O G, journaled in the top andbottom of the draw-head, the upper ends of the shafts projecting fromthe top of the drawhead. Hooks D D, projecting toward each other so thatthe point of one rests against the 5 shank of the other, are rigidlymounted on the upper ends of the shaftsG C. The hook D is provided withan arm,E, to the end of which an angle-lever, F, is pivoted, the outerend of the said angle-lever being pivoted to a hori- 0 zontal movablerod, G,whiehis suitably guided, and extends to the side of the car. Alever, H, pivoted to the rod G, extends to the top of the car, whichlever H is suitably fulcrumed at h. The inner end of the angle-lever Fis 5 above a vertically-sliding pintle, J, in the top of the draw-head,which pintle is provided at its upper end with a head, K. The pintle ispressed upward by a spring, L, surrounding it. Springs M, attached tothe draw-head at the inner end of its opening, have their free endsresting against the outer surface of the free ends of the wings B B andpress the free ends of the said wings toward each other, the saidspringspassing into grooves A in the inner sides of the draw-head.

The draw bar or linkN is provided at both ends with arrow-heads a, or atone end with an arrow-head, a, and at the other with a loop or eye, b,which latter modification is to be used it a car having the usualdraw-head is to he coupled to a car provided with my improved draw-head.Thelinks can be straight or curved to adapt them for coupling cars ofdifferent heights. The draw bar or link is provided with a cross-rod, O,to prevent inserting the 6 draw-bar too far in the draw-head.

The operation is as follows: The cars are coupled automatically, for ifthe end of the draw-bar enters the draw-head it presses the wings B Blaterally until the arrow-head has passed. Then the springs M hold theends of the wings B B against the shank of the drawbar, and prevent thelatter from being withdrawn, as the shoulders of the draw-head strikeagainst the ends of the wings; It the 7 cars are to be uncoupled, therod G is drawn in the direction of the arrow a"-that is, toward the sideof the car, either directly from the side of the car or from the top-bymeans of the lever H. Thereby the shafts U U will be turned in thedirection of the arrows and the wings B B will be swung from each other,thus permitting the draw-bar to be withdrawn.

If the rod G is moved in the inverse direction of the arrow a, the innerend of the angle-le- 8 ver F will be pressed on the head of the pintleJ, and the pintle J will be pressed down into the draw-head, and willdepress the inner end of the draw-bar, the outer end of which will beraised. The same can be raised more or less, as may be required, toguide it into the opposite draw-head.

It will be seen that the link-heads a, being wider than the slots A forthe springs M, will always be freely guided by the side walls of 5 therear chamber of the draw-head, and without liability of catchingtherein, as in other draw-head constructions.

1 am aware that it is not new to use pivoted wings with an arrow-headlink in coupling I00 cars, orto employ vertical or horizontal bars orlevers for disconnecting the coupling from the link; but

What I do claim as new and of my invention is 1. The combination, withrocking wing-carrying shafts G C, of the interlocking arms D D, attachedthereto as described, whereby the wing-shafts are so connected that theturning of one turns both, as described.

2. The combination, with the draw-head A,

of the shafts C, the Wings B B, the hooks D D, a rod for turning one ofthe shafts, and ot' the springs M, substantially as herein shown anddescribed, and for the purpose set forth.

3. The combination, with the draw-head A, of the shafts O C, the wings BB, the springs M, the hooks I) l), the arm E, and the rod G,substantially as herein shown and described, and for the purpose setforth.

4. The combination, with the draw-head A, of the shafts C U, the wingsBB, the springs M, the hooks D D, the arm E, the angle-lever F, the rodG, and the pintle J, extending through the top of the draw-head,substantially as herein shown and described, and for the purpose setforth.

5. The combination, with the draw-head A, of the shafts C G, the wings BB, the springs M, the hooks D D, the arm E, the angle-lever F, the rodG, the pintle J, the head K, and the spring L, substantially as hereinshown and described, and for the purpose set forth.

6. The combination, with the draw-head A, of the shafts G G, the wings BB, the springs M, the hooks D D, the arm E, the angle-lever F, thepintle J, the head K, the spring L, the rod G, and the lever H,substantially as herein shown and described, and for the purpose setforth.

7. A car-coupling provided with the upwardly spring-pressedslide-pintleJ,extending through the top of draw-head, whereby pressureon the top of said pintle may force down the rear end of thecoupling-link, so as to'raise the front end and guide it into anopposing draw-head, as described.

8. The combination, with a spring-pintle, J, projecting through the topof draw-head, of a lever, F, i'ulcrumed on the top of draw-head,extending over the pintle and connecting by a pivot-joint with ahandq'od, G, whereby pressure may be brought to bear on the top of saidpintle by pushing the rod G in wardly toward the draw-head, asdescribed.
